Ancient Underground City Found In Russia?

Hey guys, so a few months back I shared with you the story of adventurous geologists who had trekked far into the cold wilderness of Russia in an effort to catalogue the largest megalithic site on Earth. So remote, they are steeped in legends of snow yetis and mysterious monsters devouring all who dare to venture into these remote areas. When I shared the amazing images of these stone structures, many argued that they were natural formations. Maybe because they struggled to conceive such enormous ancient ruins in such remote places. Discoveries that seem to be many hundreds of thousands of years old. Maybe even as old as the giant sphinx. More and more is being learnt about them. With ever more daring explorations of the ruins being undertaken, a team discovered a vault in one of the stone megaliths. An access vault that led them into an artificially made stone cavern system. These underground structures are truly massive and are undoubtedly constructed by an intelligent builder. Hidden for many millennia, these caverns are not only massive, but constructed using blocks placed upon one another that are over 50 feet in length in some instances. Making these stones many thousands of tons in weight. Seemingly placed effortlessly into the shape of underground walls. This discovery is not really shed light upon how the ancients built such structures, but rather pushed their apparent capabilities farther from our understanding. Not only are these structures purpose of vast mystery, but they also contain placed stones bigger than any we've ever discovered. Even eclipsing the unfinished stone found at the ancient Chinese quarry known as Yangshan. A stone can be found here half cut away from the bedrock, in excess of 16,000 tons. Thought by scholars throughout time to have been left at the quarry due to them not being able to move it. Yet, here we have stones placed into a cave system designed which even outweigh Yangshan. This not only proves they could move them, but lift them and work them. Just how many quote natural formations are really just extremely weathered, once extremely large stone built structures? Maybe there are many stone granite hills, and even maybe mountains that dot our earth, which were before millennia of rain, grand structures of a forgotten people.
